Convector hood

ABSTRACT

A convector hood for heating and/or cooling convectors is disclosed wherein two parallel side walls are clamped together, in spaced relation to each other, by means of U-shaped stirrups. The upper and lower longitudinal edges of the side walls are each bent over on the inside to form a groove of U-shaped cross section, and the free ends of the two legs of each U-shaped stirrup are inserted in the lower grooves of the two side walls whilst projections at the upper ends of these legs project into the upper grooves. In this manner the two side walls are held together without the use of additional fastening means such as rivets or screws, and at the same time the cross pieces of the Ushaped stirrups can serve for supporting the hood on a convector. The free sides of the upper grooves may be bent over inwards perpendicularly to the side walls for supporting a covering grid and cover parts, which cover parts may be formed on end walls insertable between the side walls. Openings may be provided in the cover part and/or in the end wall for receiving a pipe or a regulating valve projecting from the convector.

Primary Examiner-William E. Wayner Assistant Examiner-William F. Tapolcai Attorney-Arnold Robinson [57] ABSTRACT A convector hood for heating and/or cooling convectors is disclosed wherein two parallel side walls are clamped together, in spaced relation to each -other, by means of U-shaped stirrups. The upper and lower longitudinal edges of the side walls are each bent over on the inside to form a groove of U-shaped cross section, and the free ends of the two legs of each U-shaped stirrup are inserted in the lower grooves of the two side walls whilst projections at the upper ends of these legs project into the upper grooves. In this manner the two side walls are held together without the use of additional fastening means such as rivets or screws, and at the same time the cross pieces of the U-shaped stirrups can serve for supporting the hood on a convector. The free sides of the upper grooves may be bent over inwards perpendicularly to the side walls for supporting a covering grid and cover parts, which cover parts may be formed on end walls inse'rtable between the side walls. Openings may be provided in the cover part and/or in the end wall for receiving a pipe or a regulating valve projecting from the convector.

6 Claims, 6 Drawing Figures PATENTED FEB? 01973 sum 1 0F 2 CONVECTOR noon This invention relates to a convector hood having a housing open underneath and closed at the top by the provision of a grid.

According to the invention a convector hood comprises a housing the upper and lower longitudinal edges of the side walls of which are bent over on the inside thus forming a groove of a U-shaped cross section and U-shaped stirrups are provided the legs of which are inserted with the free ends in the lower grooves whilst projections at the upper ends of the legs project into the upper grooves.

One embodiment of the convector hood according to the invention is illustrated by way of example on the accompanying drawings in which:

FIG. 1 shows a cross section through a convector hood,

FIG. 2 shows a section on line II-II in FIG. 1 of one end of the convector hood,

FIG. 3 is a plan ofFIG. 2,

FIG. 4 shows a cover part for the upper side of the hood,

FIG. 5 is a perspective view of the hood and FIG. 6 shows a perspective an end wall of the convector hood.

The convector cover hood has side walls 1 made of sheet metal which are bent over at the upper and lower longitudinal edges on the inside to form grooves 2 and 3-respectively which are U-shaped in cross section. The edge 4 of the upper grooves 2 is bent inwards perpendicular to the side wall.

For the detachable connection of two side walls belonging to a hood, U-shaped stirrups are provided which have two sides or legs 5 and the cross piece 6 as well as upwardly directed projections 7.

Whilst the cross piece 6 holds the two side walls 1 spaced apart from one another it serves at the same time for supporting the hood on a convector heater, not shown.

The free lower ends of the legs 5 and the projections 7 fit tightly in the grooves 2 and 3 of the side walls in which they are inserted.

The end walls (FIGS. 2, 3 and 6) have edge parts 9, 10 and 11 running perpendicularly to a middle part 8. The upper edge part or cover part 10 also carries at the front end a part 12 projecting vertically downwards.

The edge parts 10 and 11 are provided at the ends with cut out portions 13 and 14 (FIG. 6) which are so dimensioned that the edge parts of the side walls formed into the grooves 2 and 3 fit into the cutout portions 13 and 14 respectively.

The part 12 of the cover part 10 lies on the edges 4 when the edge parts 9 are inserted fitting tightly between the side walls 1.

The middle part 8 of the end wall and a part of the edge parts 10 and 11 may have a cut out portion 15 (FIG. 3 and 6) which allows the end wall to be attached even when a pipe from the convector projects upwards through the hood.

According to the position of this pipe a separate cover part consisting of a plate 16 (FIG. 4) with a cut out portion 15 can be placed between the side walls 1 on the edges 4. The cut out portion 15 may also serve as a passage for the regulating valve of the convector.

Between the side walls 1 and the end walls on the plate 16 a grating is placed on the edges 4, the grating consists of longitudinal bars 17 and cross bars 18 connecting same. This grating may be divided in the longitudinal direction according to the length of the hood.

Instead of the grating an insert made of perforated sheet metal, wire netting and the like may be used.

The side walls 1 are made in specified manufactured lengths and cut according to the different convector lengths or also lengthened by extension pieces. In the latter case at the abutting place a U-shaped stirrup is inserted in the grooves 2 and 3 so as to overlap half way across the abutting pieces.

By simple fitting of the parts of the hood into one another without the use of rivets or screws its assembly for any length of convector is easily possible. The individual parts of the hood may be kept in stock and are immediately available.

The convector hood described may be used as cover for heating or refrigeration (air condition) convectors.
